About game: Sneak up on enemy ships and try sinking as many as you can by using each of your three directional torpedoes. Each level will require you to sink a certain amount of ships, so it is critical that your shots are accurate. You are also very limited in health and fuel, but periodically a helicopter will drop a resupply package that you can use to resupply both your fuel and health. Blow up enough ships and you will earn money that you can use to buy upgrade in armor, speed, fuel efficiency, and torpedoes.
